Patent DE-4128821-A1 (DE)
Inventor: GRAS JUERGEN DIPL ING
IPC: F02M51/06
Filed: 1991-08-30
Abstract: Prior art electromagnetically actuatable injection valves have a plurality of obstacles to flow along the flow path of the fuel through the injection valve in the form of narrowed cross-sections. These narrowings act as barriers for rising vapour bubbles which are formed by the effect of heat after the internal combustion engine has been stopped and adversely affect the hot-starting properties. The novel injection valve has a much dethrottled flow path. Two guide sections (47, 48) of a valve needle (29) each have four concave overflow surfaces (50). A securing body (39) has tow concave overflow surfaces (56). The concave shape of the overflow surfaces (50, 56) enlarges the cross-section of the flow path in these regions. In addition, the cross-section of the flow path is increased by a longitudinal drilling (62) and transverse drillings (63, 65) in the valve needle (29). The novel injection valve is especially suitable for fuel injection installations in mixture compressing, external-ignition internal combustion engines.
